On the machine I have set the local names to point to 192.168.0.6 in the hosts 
file.

I have not set up any dns except externally. I suppose that packets are arriving 
and being routed via NAT into the internal server which claim to be addressed to 
the router's external address.

Can I add some simple route that fixes this?
